Question:

I have a tracker trailstar boat trailer. The hub on the spindle for the grease seal measures 1.68. Do I need this 1.719 grease seal. This is the one they suggest and it is a triple-lip seal. I am getting water in my hub.

Expert Reply:

There are grease seals with inner diameters of 1.687 inches, # 168255TB, or 1.688 inches, # 168233, that would be a better fit. If the outer diameters match the inner hub bore diameter then you can use one of them instead.

Seal # 168255TB has an inner diameter of 1.687 inches and outer diameter of 2.561 inches.

Seal # 168233 has an inner diameter of 1.688 inches and outer diameter of 2.332 inches.

The seals in set # RG06-050 have an outer diameter of 2.565 inches so that would mean # 168255TB would be the best option. That 4 thousands of an inch difference wouldn't be an issue.
